provide an array to monitor and then copy the user state to the kernel state Kernel-state linear loop monitoring array, which needs to traverse the entire array each time The kernel discovers that the file descriptor state conforms to the operation result and returns it So the socket we are monitoring to be set to non-blocking, only in this way to ensure that the advantages are not blocked Basic platforms Support weaknesses Every time you call Select, you need to copy the FD collection from the

Select Module function: Select System call is used to detect multiple file description state changes, the program will always wait in the select until the time-out or the monitored file descriptor in one or more state changes. Select function: Select (Rlist,wlist,xlist[,timeout]), return value: (rlist,wlist,xlist) Rlist: Read the socket list to determine if there is a readable socket;

. $ Service_host is usually a public IP address. The configuration of VNC proxy is relatively simple. You only need to set the host and port on which it listens. The details are as follows: Novncproxy_host = $ service_host is usually a public IP address. Maid = 6080 Xvpvncproxy_host = $ service_host is usually a public IP. Xvpvncproxy_port = 6081 Take novncproxy as an example to see how it is implemented: Class novawebsocketproxy (websockify. websocketproxy): # inherits from websocketprox

kernel returns to the process immediately, and an error is returned if the data is not ready. After the process returns, it can do something else before initiating the recvform system call. Repeat the above process and iterate through the recvform system calls. This process is often called polling. Poll the kernel data until the data is ready, and then copy the data to the process for data processing. It is important to note that the process of copying data is still a blocked state　　Therefore,

, a list of file descriptors is returned, indicating that the files have an event arrival. The following simple program means waiting for input from standard input: Rlist, wlist, elist = Select.select ([Sys.stdin], [], []) print sys.stdin.read () The three parameters of the Select method are list types, which represent read events, write events, error events, and the same method return value is also three lists, which contains the events (read, write

(this limit can be improved by modifying the macro definition or recompiling the kernel) And because the FD of select is placed in the array, and each time the entire array is linearly traversed, when there are many FD, the overhead is very high Python Select The function that calls Select is Readable,writable,exceptional = Select.select (rlist, wlist, xlist[, timeout]), and the first three parameters are three lists, respectively.

diagram to indicate the file descriptor events we want to pay attention to. In Python, the list is used to indicate the file descriptor we monitor. When an event arrives, the returned list of file descriptors indicates that these files have events. The following simple program is to wait for the input to be obtained from the standard input: rlist, wlist, elist = select.select( [sys.stdin], [], [] )print sys.stdin.read() The three parameters of the

copy the fd set from the user state to the kernel state. This overhead is very high in many cases of fd. There is a maximum limit on the number of fd instances that a single process can monitor. the default value is 1024 in linux (you can increase this limit by modifying the macro definition or re-compiling the kernel) In addition, since select fd is placed in an array and the entire array needs to be traversed linearly each time, the overhead is also high when fd is large.
